  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 38E , additional homework tip  1

Expert Solution

Answer to Problem 38E

The area of the triangle is 9 sq. units .

Explanation of Solution

Given information:

The figure,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 38E , additional homework tip  2

Formula used:

Area of a triangle is half into the product of its base and height. So, if b is the base and h is its height, area of triangle is calculated as,

  A=12bh

Calculation:

Consider the given figure,

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 1.8, Problem 38E , additional homework tip  3

In the above figure, it is observed that the base of triangle is measured as 6 units and its height is 3 units.

Recall that the area of a triangle is half into the product of its base and height. So, if b is the base and h is its height, area of triangle is calculated as,

  A=12bh

Apply it,

  A=12bh=1263=1218=9 sq. units

Thus, area of the triangle is 9 sq. units .
